What did the Trader Joe's lawsuits find about their Low Acid coffee?

Independent testing found Trader Joe's Low Acid Dark French Roast at pH 5.44 (below the 5.5 clinical threshold) with approximately 50% less caffeine than regular coffee — consistent with a half-caff product — with zero label disclosure.

How do I know if a low acid coffee is genuinely low acid?

Look for independent university testing, a verified pH above 5.5, full caffeine disclosure, and third-party certification like LACCSA. Puroast is the only brand verified by two universities and protected by a USPTO patent.

What would change if Puroast wins the lawsuit?

Brands would be required to meet a scientifically defined pH threshold to use the low acid label. Any process that affects caffeine levels would require clear disclosure. Consumers with acid reflux and GERD could finally trust what they are reading on the bag.

How many Americans are affected by this issue?

85 million Americans live with acid reflux, GERD, or heartburn — many of whom choose low acid coffee on medical advice. All of them are potentially harmed when that labeling is fraudulent.
